SensorWorx SWX-221-1 Dual-Tech Ceiling Occupancy Sensor, 360°, 500 Sq Ft, Low Voltage

Product Overview

The SensorWorx SWX-221-1 is a ceiling-mounted dual-technology occupancy sensor designed for low-voltage lighting control systems. It combines passive infrared (PIR) and acoustic sensing to reliably detect room occupancy and signal a connected power pack to control lighting based on occupancy, making it ideal for offices, classrooms, and other commercial environments seeking enhanced energy efficiency.

Key Features & Design

• Functionality: Detects occupancy using dual-technology sensing (PIR and acoustic) and signals a connected power pack to control lighting based on room activity.
• Installation context: Ceiling-mounted sensor suitable for both retrofit and new installations in low-voltage lighting control networks within offices, classrooms, and other commercial spaces.
• Notable specifications: This sensor uses dual-technology sensing (PIR and acoustic) with 360° coverage up to 500 sq ft, operates on low-voltage systems, and is designed for ceiling-mounted installation with occupancy-based control through a connected power pack.
• Contractor-relevant details: Provides reliable occupancy detection with dual technology, reducing false triggers and energy waste while offering straightforward integration into existing low-voltage lighting systems for faster, cost-effective retrofits.

Performance / Benefits

In practical use, the SWX-221-1 delivers dependable, room-wide lighting control that responds to real-time occupancy. Its ceiling-mounted design preserves space and sightlines while delivering 360° coverage up to 500 sq ft, making it well-suited for open offices, classrooms, conference rooms, and other commercial areas. The combination of PIR and acoustic sensing enhances reliability in environments with varying lighting conditions or ambient noise, helping ensure lights operate only when people are present and contributing to energy savings and reduced operating costs over time.
